1. The Larson family is traveling from Michigan to Florida at an average speed of 60 miles per hour. Write an equation for a rule you can use to calculate the distance they have traveled after any given number of hours. answer: The equation rule for the Larson family's travel distance when going on 60mph is 60h=d. 60h means 60 times hours, = means is, and d means the distance. In words, this means: '60timeshoursis the distance.'
2. What are the advantages to having an equation to represent the Larson family's situation? What are the advantages to having a table? A graph? answer: There's an advantage of easily getting an answer when you're using a equation. It's because it already shows what to do for you so you just need to follow it. As a graph, ther's an advantage of seeing the pattern (which is basicly a straight line) of the distnace and speed. As a table, there's an advantage of already knowing how far you will go in what hour by giving out a list of those answers. It's like an answer list you would use to check any mistakes. Summary:
In this investigation nd unit, I learned about equations and how to use, make, and display them. Equations always need an '=' sign and then numbers and letters. Equations are used for getting answers easily and to find an answer with any # of anything. It's useful when you want a pattern of a stiuation, like the distance traveled in a certain amount of speed. Just get the equation, and you'll get the answer! The equation is ussually this style: #x=f. A equal sign, and 2 different #(s) or letter(s) on the sides.
